Step-by-step explanation:

Answer:

30189.155

Step-by-step explanation:

Recall the compound interest formula :

A = P(1 + r/n)^nt

P = principal = 10000

r = rate = 3.7% = 0.037

n = quarterly = 4

t = 30

A = 10000(1 + 0.037/4)^30*4

A = 10000(1 + 0.00925) ^120

A = 10000(1.00925)^120

A = 10000 * 3.0189155

A = 30189.155

Answer:

[tex]\frac{15}{64}[/tex] of the pie

Step-by-step explanation:

Whole numbers refer to a collection of natural numbers together with 0.

Fraction refers to part of a whole.

Part of an apple pie left from a dinner = [tex]\frac{3}{8}[/tex]

Part of an apple eaten by Victor tomorrow is equal to  [tex]\frac{5}{8}[/tex] of the pie that was left

So,

Part of an apple eaten by Victor tomorrow = [tex]\frac{5}{8}(\frac{3}{8})=\frac{15}{64}[/tex] of the pie

Answer:

23

Step-by-step explanation:

The number of points that she would need to score in her 12th game in order to decrease the interquartile range by 1 point is; 23

An interquartile range is one of the measure of variability that measures the spread of middle 50% of the data.

The formula to calculate interquartile range is:

IQR = Q₃ - Q₁

where;

Q₃ is third quartile

Q₁ is first quartile

The given points when arranged in increasing order gives us:

13, 15, 17, 18, 20, 20, 21, 22, 24, 25,27

Q₁ is the (n + 1)/4 terms = 3rd term.

Thus; Q₁ = 17

Q₃ is 3(n + 1)/4 term = 9th term.

Thus; Q₃ = 24

Then; IQR = 24 - 17

IQR = 7

The desired interquartile range should decrease by 1 point. Thus;

Desired IQR = 7 - 1 = 6.

To find the score of the 12th game, let us try  23 points as the score of the 12th game:

Thus;

Q₁ = 17.5

Q₃ = 23.5

IQR = 23.5 - 17.5

IQR = 6

Thus, required number of points is 23.

Answer:

which 1st page or 2nd page

Answer:

Step-by-step explanation:

L₁: y = 5x + 1

Slope of L₁ = 5

L₂: Did you mean 2y - 10x +3 = 0 ?

2y = 10x - 3

y = 5x - 1.5

Slope of L₂ = 5

L₁ and L₂ have the same slope, so the lines are parallel.

Answer:

yes 6/5 is greater

Problem solving:

first you need to simply the fractions and see which one is bigger.

2/3 = 0.667

6/5 = 1.2

-Sumin <3

Answer:

Yes

Step-by-step explanation:

When you look at the two fractions, we can immediately tell that the first is over 1 and the other is not one. However, if we wanted to see how much greater 6/5 is compared to 2/3, then we could find the common denominator and then subtract the 2/3 from the 6/5.

6/5 - 2/3

18/15 - 10/15

8/15.

This can't be simplified.

Thus, 6/5 is 8/15 greater than 2/3.

Hope that this helped and everything works out. You can do this same method with any two fractions if your not sure if one is greater than, equal to, or less than any other number and what the difference is between them.

Answer:

-12

Step-by-step explanation:

First you add five to the 19 and get 24 and then you divide -2x by 24 and you get -12

Answer:

x=-12

Step-by-step explanation:

-2x-5=19

+5 to both sides

-2x=24

÷-2 to both sides and you get -12

Answer:

Slope = 3

Y intercept = 1

Step-by-step explanation:

Slope intercept form is

y = mx+b where m is the slope and b is the y intercept.

So in your question

-3x+y=1

add 3x to each side to get

y = 3x+1

3 is m

1 is b

so the slope is 3

the y intecept is 1

Step-by-step explanation:

A parallelogram is a polygon (has four sides and four angles) in which opposite sides are parallel and equal to each other. Opposite angles are equal and consecutive angles are supplementary. Also, the diagonals bisect each other.

BC = AD (opposite sides are equal)

BC = 10 cm

m∠BCD = m∠DAB (opposite angles are equal)

m∠BCD = 120°

AB = DC (opposite sides are equal)

AB = 5 cm

EB = DE (diagonals bisect each other at point E)

EB = 6.1 cm

Answer:

BC = 10

m∠BCD?=120

AB=5

EB=6.1

Answer:

Step-by-step explanation:

27 is the "center" of a range of measurements of the height of the guard rail.  The height could be as much as 30 inches or as little as 24 inches.  The absolute value operator encloses "x - 27," where 27 is the "center."  The acceptable excess or acceptable deficiency is 3 inches.  

So now we can eliminate possible answers B and C, in both cases because 27 is inappropriately greater than 3.

Narrowing down our choices, we have h + 27 and h - 27 inside the absolute value operator.  27 is a positive quantity (height of the guard rail), so the inequality showing +27 as the "center" is correct; that is

D:  |h - 27| ≤ 3 (measurements in inches).

Answer:

Smallest to largest:

The circle with a diameter of 19

The circle with a circumference of 87.92

The circle with the area of 1,040.09

The circle with the radius of 27

Step-by-step explanation:

-The formula for the area is pi x r^2

-The diameter is double the radius, meaning divide it by 2 to get the radius.

-The formula for a circumference is 2 x pi x r meaning, do the reverse to get the radius. (87.92 divided by pi and then by 2 gives you the radius.)

-pi is equal to 3.14

Step-by-step explanation:

The first and only rule really is to factor these down to their primes and then apply a very simple rule

For every prime, take out 1 prime for every prime under the root sign that equals the index. The rest are thrown away.

That's very wordy. Let's try and see what it means with an example

Take sqrt(27) The index is 1/2 (square root) That means we need two threes in order to apply the rule.

sqrt(27) = sqrt(3 * 3 * 3 ) For every two primes take out 1 and throw one away.

sqrt(27) = 3 sqrt(3) You can't take out that 3rd 3.

64 = 2 * 2 *2 *2 *2 * 2

4th root 64 =  2*2*2 *2 * 2 *2

for every 4th root, you get to take 1 out and throw three away.

4th root 64 = 2 fourth root (2*2)

4th root 64 = 2 fourth root (4)

- 189 = -  3 * 3 * 3 * 7

cuberoot (- 189) = For every 3 roots, you get to pull 1 out and throw the other two away.

3 cube (- 7) is your answer.

72 = 2 * 2 * 2 * 3 * 3

cube root (72) = 2 cube root(9) You don't have enough threes to do any more than what is done.
